OIL-PUMP.

SPECIFICATION forming part of Letters Patent No. 345,431, dated July 13,1886.

Application filzd May 8, 1886. Serial No. 201,573. (ModeL) To aZZ whomit may concern.-

Be it known that 1, PAUL HIGHT, a citizen of the United States,and aresident of Spencer, in the county of Owen and State of Indiana, haveinvented certain new and useful Improvements in Oil-Pumps; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings,which form a part of this specification,and in which Figure 1 is a perspective view of a barrel provided with myimproved oil-pump. Fig. 2 is a vertical sectional view of the same. Fig.3 is a perspective detail view of the pump removed from the barrel. Fig.4 is asectional detail view of the pump inserted in a barrel.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of oil-pumps which may beinserted through the bung-hole of a ba1'rel,and which are provided witha suitable dripping apparatus, whereby the oil dripping from the nozzleof the pump and running over in filling oil-cans may be carried backinto the barrel and it consists in the improved construction andcombination of parts of such a pump, as hereinafter more fully describedand claimed.

In the accompanying drawings,the letter A indicates a screw-threadedbushing having a polygonal flange, B, at its upper end, and adapted tobe screwed into the bung-hole of a barrel or cask, and the inner side ofthis bushing is formed with a female screw-thread, G,

into which a long screw-threaded sleeve, D,

may fit. This sleeve is formed at its upper end with a flange, E,adaptedto be engaged by asuitable wrench for turning it, and the tube F of thepump is secured, by solder or otherwise,within this sleeve.

The upper end of the pump-tube is formed with an enlarged chamber,G,having a nozzle, H, and the piston I, having the piston-rod J. Anupwardly-opening valve, K, reciprocates within the tube, having a handleat its upper end, as shown at L,while the lower end of the tube isprovided with an upwardly-opening valve, M.

A drip-pan,N,is secured around the pumptube, and has an aperture,0,atone side of the tube,which aperture opens into adownwardlyextendingchannel,P,passing parallel withthe pump-tube, and flush with the same,and the lower end. of the channelopens through the lower end of thesleeve in which the pumptube is secured.

WVhen the pump is to be used,the bung-hole of the barrel is opened,whereupon the screwthreaded bushing is screwed home in the bunghole, andthe pump-tube, with its attached sleeve,is thereupon inserted throughthe bushing and the screw-threaded sleeve screwed into the bushing to adepth such as will allow the pump to extend to the bottom of saidbarrel, the said sleeve being of asufficient length to be screwed downin the bushing at different ,heights, and thus be adjusted to barrels orcasks of different sizes. 7

It will be seen that the oil may be pumpedup by the pump and filled intocans or other suitable vessels placed upon the drip-pan, and all oilwhich may overflow from the said vessels, or which may drip from thenozzle of the pump, may pass down into the barrel again through thechannel, passing from the aperture in the drip-pan into thescrew-threaded sleeve.

The pump may be of any desired construction, and the drip-pan may bemade eitherflat, as shown in the drawings, having flanges around itsedges,or it may be made dished toward the aperture at the side of thepump tube, so as to cause the oil to return to the barrel with greaterease. It will be seen that by this construction the trouble of fillingthe oil from a barrel into a can having the filling-pump may be avoided,as the oil may be served out in small quantities directly from thebarrel, and all drip may return into the barrel.

The sleeve upon the pump-tube being long, the said sleeve may beadjusted at different heights in the bushing, so that the pump may beused in barrels or casks of different sizes and diameters,and at thesame time the pump may first be used so as to draw the oil from near thetop, and the tube and sleeve may be lowered as the oil isconsumed,allowing the oil to settle undisturbed, and admitting of atlast pumping all the sediment out of the barrel without any danger ofmixing it with the clear oil.

Although this pump is preferably intended Ice for use in retailing, orin serving oil in small quantities, and especially coal-oil or similaroils used for illuminating purposes, the pump may be used for drawingall kinds of oil and other fluids which do not suffer any damage frombeing exposed to the air through the channel opening from the drip-pan,and fluids which are not damaged by being drawn are again allowed to runback into the barrel or cask.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States In an oil-pump, the combination of abush ing having an external and an internal screwthread,and adapted tobe screwed intoa bung-
